Open claude_desktop_config.json and add the freelance server configuration:
{
"mcpServers": {
"freelance": {
"command": "uv",
"args": [
"run",
"--with", "mcp",
"--with", "python-dotenv",
"--with", "langchain-groq",
"--with", "pydantic",
"/absolute/path/to/your/freelance_server.py",
"stdio"
],
"env": {
"GROQ_API_KEY": "your_groq_api_key_here",
"MCP_AUTH_TOKEN": "your_optional_auth_token",
"OWNER_COUNTRY_CODE": "1",
"OWNER_PHONE_NUMBER": "5551234567"
}
}
}
}Important Notes:
Replace
/absolute/path/to/your/freelance_server.pywith the actual full path to yourfreelance_server.pyfileOn Windows, use double backslashes:
C:\\Users\\YourName\\MCPs\\freelance_server.pyOn Mac/Linux, use forward slashes:
/Users/YourName/MCPs/freelance_server.pyReplace all placeholder values with your actual API keys and phone number
Windows Example:
{
"mcpServers": {
"freelance": {
"command": "C:\\Users\\YourName\\.local\\bin\\uv.EXE",
"args": [
"run",
"--with", "mcp",
"--with", "python-dotenv",
"--with", "langchain-groq",
"--with", "pydantic",
"C:\\Users\\YourName\\MCPs\\mcp-server-1\\freelance_server.py",
"stdio"
],
"env": {
"GROQ_API_KEY": "gsk_xxxxxxxxxxxxxxxxxxxxx",
"MCP_AUTH_TOKEN": "your_optional_auth_token",
"OWNER_COUNTRY_CODE": "1",
"OWNER_PHONE_NUMBER": "5551234567"
}
}
}
}Step 5: Restart Claude Desktop
Completely quit Claude Desktop (not just close the window)
Reopen Claude Desktop
The freelance server should now be available
Step 6: Verify Installation
In Claude Desktop, try asking:
"Search for Python freelance gigs under $500"
"Show me current freelance market trends"
"Validate the owner phone number"
Troubleshooting Claude Desktop Integration:
Server shows as "failed":
Check the logs: Open the "Open Logs Folder" from the error
Look for
ModuleNotFoundError- means dependencies are missingVerify all
--withpackages are included in args
"Server disconnected" error:
Ensure
stdiois the last argument in args arrayCheck that the path to
freelance_server.pyis absolute and correctVerify
uvis installed: Runuv --versionin terminal
Environment variables not loading:
Double-check the
.envfile exists in the same directory asfreelance_server.pyVerify env values in
claude_desktop_config.jsonmatch your.envfileMake sure there are no extra quotes or spaces
Finding uv path (Windows):
where.exe uvFinding uv path (Mac/Linux):
which uv
Alternative: Manual Installation Method
If you prefer to install dependencies globally instead of using --with flags:
# Install dependencies globally with uv
uv pip install mcp python-dotenv langchain-groq pydantic
# Then use simpler config
{
"mcpServers": {
"freelance": {
"command": "uv",
"args": [
"run",
"/path/to/freelance_server.py",
"stdio"
],
"env": {
"GROQ_API_KEY": "your_key_here",
"OWNER_COUNTRY_CODE": "1",
"OWNER_PHONE_NUMBER": "5551234567"
}
}
}

Available Tools
17 toolsanalyze_profile_fitC
Analyze how well a user profile fits a specific gig
Args:
profile_data: User profile information
gig_id: ID of the gig to analyze fit for
| Name | Required | Description | Default |
|---|---|---|---|
| gig_id | Yes | ||
| profile_data | Yes |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden, and it says nothing about whether the analysis is read-only, how expensive or slow it is, what criteria drive the fit score, or whether profile_data is persisted. For an evaluation tool with a nested free-form input object, this is a substantial gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The one-line purpose is appropriately front-loaded and the whole definition is short. The Args block, however, consumes space while conveying no information beyond the parameter names already in the schema, so it does not earn its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values need not be described. But for a two-parameter tool with a nested object input and zero annotations, the description supplies no behavioral, usage, or parameter detail, leaving the agent under-informed before invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the Args block only restates the parameter names: 'profile_data: User profile information' and 'gig_id: ID of the gig to analyze fit for'. Nothing is said about the expected shape, keys, or units of profile_data despite it being an open nested object.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The first sentence gives a specific verb (analyze) and resource (profile vs. gig fit), so an agent can tell what the tool does. However, it does not distinguish itself from close siblings such as optimize_profile, get_smart_recommendations, or calculate_pricing_strategy, which could plausibly be selected for an overlapping task.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no statement of when to use this tool versus the many profile- and gig-related siblings. The only implicit guidance is that a profile and a gig id are both required, which the schema already enforces.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
analyze_skill_demandB
Analyze market demand for specific skills
Args:
skills: List of skills to analyze
use_real_api: Use real API or mock data
Returns:
Market insights for each skill including demand, rates, and trends
| Name | Required | Description | Default |
|---|---|---|---|
| skills | Yes | ||
| use_real_api | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It implies a read-only analysis but never states that changes are non-destructive, what data source/credentials are needed, or how the real-vs-mock API mode behaves operationally. Only the mock/real toggle hints at any behavioral trait.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Docstring structure is compact and front-loads the purpose ahead of Args/Returns. Every line is short, though the Args section adds little beyond the schema field names.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return-value documentation is not strictly required, and the description still sketches the shape (demand, rates, trends). For a two-parameter, one-required analysis tool this is largely complete; only usage routing and behavioral context are thin.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description is the only source for both parameters. It briefly explains 'use_real_api' as real vs mock data (adding some meaning over the bare schema) but restates 'skills' trivially as 'List of skills to analyze' without format, count, or example expectations.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('Analyze market demand for specific skills'), which is concrete and actionable. It doesn't however distinguish itself from adjacent siblings like calculate_pricing_strategy or analyze_profile_fit, so an agent must infer which analysis tool fits.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No when-to-use guidance, no prerequisites, and no named alternatives. With 17 siblings that overlap in the analytics space (analyze_profile_fit, calculate_pricing_strategy, research_client_intel), the description leaves routing entirely to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
calculate_pricing_strategyB
Calculate optimal pricing strategy for a specific gig using AI
Args:
gig_id: ID of the gig
skills: Your skills
user_rate_min: Your minimum hourly rate
user_rate_max: Your maximum hourly rate
success_rate: Your historical success rate (0-100)
Returns:
Optimal pricing recommendation with strategy
| Name | Required | Description | Default |
|---|---|---|---|
| gig_id | Yes | ||
| skills | Yes | ||
| success_rate | No | ||
| user_rate_max | No | ||
| user_rate_min | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full behavioral burden, but it only states that the tool calculates a recommendation using AI and returns an optimal pricing recommendation. It does not disclose side effects, rate limits, auth requirements, or whether the operation is read-only.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the core purpose, followed by a clear Args and Returns structure. Every sentence is informative and there is no redundant or wasted text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers all parameters and gives a high-level return statement, which is helpful given the 0% schema coverage. However, with no annotations, it should provide more behavioral context (e.g., safety, side effects) and usage guidance to fully support correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It does list all five parameters with brief explanations, including the 0-100 range for success_rate, which adds meaning beyond the schema. However, it does not clarify formats or types for some parameters (e.g., skills as an array).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('Calculate') and resource ('pricing strategy') for a specific gig using AI. It is clear what the tool does, but it does not differentiate itself from sibling tools like negotiate_rate or analyze_skill_demand.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explain when to use this tool versus alternatives, nor does it provide any prerequisites or exclusions. Usage is only implied by the purpose statement, leaving the agent to infer context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
code_debugB
Debug and fix issues in a code file
Args:
file_path: Path to the code file to debug
issue_description: Description of the issue to fix
fix_type: Type of fix (auto, manual, suggest)
backup: Whether to create a backup before making changes
| Name | Required | Description | Default |
|---|---|---|---|
| backup | No | ||
| fix_type | No | auto | |
| file_path | Yes | ||
| issue_description | Yes |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions a 'backup' parameter but does not explain its default behavior (true), nor does it disclose permission requirements, reversibility, or rate limits. The description implies a mutation but lacks crucial behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the main action and neatly structured with an Args section. Every sentence is purposeful and no information is wasted.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers parameters but lacks behavioral details (e.g., what 'auto' vs 'manual' means, consequences of backup). With no annotations and an output schema, the description is adequate but leaves gaps in expected behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description lists all four parameters and provides brief explanations, effectively compensating for the 0% schema description coverage. It clarifies the meaning of 'fix_type' and 'backup', adding value beyond the schema's basic types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb+resource ('Debug and fix issues in a code file'), which is clear. However, it does not differentiate from the sibling 'validate' or 'code_review', leaving ambiguity about when to choose this tool over those.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'validate' or 'code_review'. There is no mention of prerequisites, context, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
code_reviewB
Review code file and provide feedback using LLM analysis
Args:
file_path: Path to the code file to review
review_type: Type of review (general, security, performance, style)
| Name | Required | Description | Default |
|---|---|---|---|
| file_path | Yes | ||
| review_type | No | general |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits, but it only mentions 'using LLM analysis,' which hints at AI-driven processing but omits critical details like whether the operation is read-only, requires specific permissions, has rate limits, or returns structured feedback. The description lacks transparency about side effects and operational constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded: a single summary sentence followed by a compact Args section. Every sentence serves a purpose, and there is no redundant or filler content. The structure is easy to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 parameters) and the presence of an output schema, the description covers the basics of purpose and parameters. However, it falls short on usage guidelines and behavioral transparency, which are important when annotations are absent. It is adequate but incomplete for an agent to fully understand when and how to invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, so the description must explain parameters. It does so effectively: 'file_path: Path to the code file to review' and 'review_type: Type of review (general, security, performance, style)' gives clear meaning and even enumerates possible values. It could specify format expectations for file_path, but overall it compensates well for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Review code file and provide feedback using LLM analysis.' This specifies a verb (review) and resource (code file), making it easy to distinguish from general utilities. However, it does not differentiate from sibling tools like 'validate' or 'code_debug' that might also involve code analysis, so it's not a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. There is no mention of scenarios where code_review is preferred over validate or code_debug, nor any prerequisites or exclusions. The absence of any usage context warrants a low score.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

No annotations provided, so description carries full burden. It doesn't disclose permissions required, whether creation is idempotent, what happens on duplicate, or any rate limits. Only the parameter list is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Front-loaded with purpose, then a clean list of Args. It's appropriately sized with no wasted words, though the formatting as a code block with indentation is slightly informal.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 7-parameter required-everything tool with output schema available, the description covers parameters but misses behavioral context like return value, side effects, or validation rules. It's minimally adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description must compensate. It briefly explains each parameter's meaning (e.g., 'Full name', 'Professional title'), which adds some clarity beyond the schema's titles, but lacks format details (e.g., skills_data structure, rate currency). This is a modest improvement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clear verb+resource: 'Create a new user profile'. It distinguishes from siblings like validate or optimize_profile, though it doesn't explicitly name alternatives. The purpose is unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like validate or optimize_profile. It simply states what it does without context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
generate_portfolioC
Auto-generate professional portfolio
Args:
name: Your name
title: Professional title
skills: List of skills
years_experience: Years of experience
project_history: List of past projects
Returns:
Generated portfolio in HTML and Markdown
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | ||
| title | Yes | ||
| skills | Yes | ||
| project_history | No | ||
| years_experience | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It discloses the output formats (HTML and Markdown), but says nothing about side effects, persistence, whether a profile must exist first, permissions, or how long generation takes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Short, front-loaded, and free of filler; the Args/Returns split is readable. It is slightly over-structured for five trivially labeled parameters, but nothing is wasteful.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so the Returns line is redundant rather than harmful. However, with 0% schema coverage and three required parameters, the description leaves the agent without format expectations, optionality, or default values.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate, and it largely restates the schema titles ('name: Your name', 'skills: List of skills'). Useful additions like which params are optional, the default of 3 years_experience, and the shape of project_history objects are absent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('Auto-generate professional portfolio'), so an agent knows exactly what it produces. No sibling tool overlaps with portfolio generation, so differentiation isn't needed, but it also makes no explicit distinction from the nearby generate_proposal.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no context on when to call this versus alternatives such as generate_proposal or create_user_profile, no prerequisites, and no indication of when generation is inappropriate. The only framing is the name itself.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
generate_proposalB
Generate a personalized proposal for a specific gig using Langchain ChatGroq
Args:
gig_id: ID of the gig to generate proposal for
user_profile: User profile information
tone: Tone of the proposal (professional, friendly, confident)
include_portfolio: Whether to include portfolio references
custom_message: Additional custom message to include
| Name | Required | Description | Default |
|---|---|---|---|
| tone | No | professional | |
| gig_id | Yes | ||
| user_profile | Yes | ||
| custom_message | No | ||
| include_portfolio | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It does not disclose whether the generated proposal is persisted, sent to the client, or merely returned; nor does it mention latency, token cost, or that LLM generation is non-deterministic. The mention of Langchain ChatGroq is the only faint signal, which is well short of what a zero-annotation tool needs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the core purpose and then uses a compact Args list with one line per parameter. There is no filler prose; the only minor waste is the toolchain name in the opening sentence.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With five parameters, a nested user_profile object, no annotations, and an output schema that already covers return values, the description adequately covers input semantics but omits behavioral context an agent needs ā side effects, persistence, and any prerequisites for a valid gig_id or complete user_profile.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% ā the input schema only supplies titles and defaults ā so the Args block is doing real work. It documents all five parameters, including the allowed tone values (professional, friendly, confident) and the purpose of user_profile, custom_message, and include_portfolio, which the schema leaves entirely opaque.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The first line names a specific verb and resource ('Generate a personalized proposal') scoped to 'a specific gig', which cleanly separates it from siblings like generate_portfolio, create_user_profile, or research_client_intel. The trailing 'using Langchain ChatGroq' is an implementation detail that adds no selection value but does hint that output is LLM-generated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no when-to-use, when-not-to-use, or alternative-routing guidance. An agent cannot tell from this text whether to call generate_proposal before or after analyze_profile_fit or calculate_pricing_strategy, nor whether it should be paired with send_notification.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_smart_recommendationsB
Get AI-powered gig recommendations with success prediction and optimal pricing
Args:
skills: List of skills to match against
max_budget: Maximum budget filter
min_budget: Minimum budget filter
platforms: Platforms to search
top_n: Number of recommendations to return
use_real_api: Use real API or mock data
Returns:
AI-powered recommendations with win probability, optimal pricing, and strategy
| Name | Required | Description | Default |
|---|---|---|---|
| top_n | No | ||
| skills | Yes | ||
| platforms | No | ||
| max_budget | No | ||
| min_budget | No | ||
| use_real_api | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It usefully discloses that the tool can operate against real or mock data ('use_real_api') and that results include win probability, optimal pricing, and strategy. It does not state cost, latency, rate limits, or whether recommendations are persisted, leaving real behavioral gaps for a 6-param analysis tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The purpose lands in the first sentence, and the Args/Returns blocks are compact with no filler. The list-style formatting is slightly mechanical but appropriately sized for a six-parameter tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so the Returns sentence is largely redundant, and the definition never routes the agent between this tool and its many siblings in the recommendation/pricing family. The bare one-line argument glosses leave the highest-complexity decisions (platform selection, budget semantics) underspecified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate and it does partially: it glosses all six parameters, e.g. top_n as 'Number of recommendations to return'. However the glosses largely restate the parameter names, and it omits meaningful semantics such as what a null platforms/budget means (all platforms, no bound) or the units/currency of the budgets.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('Get AI-powered gig recommendations') plus the differentiating payload (success prediction, optimal pricing). It is distinguishable from search_gigs at a high level, but never explicitly contrasts itself with that sibling, so a 4 rather than a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no indication of when to use this tool versus search_gigs, calculate_pricing_strategy, or analyze_skill_demand, and no prerequisites or exclusions are stated. The only usage-adjacent hint is the use_real_api flag, which is a mode switch rather than guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
negotiate_rateB
Generate rate negotiation strategy and message using Langchain ChatGroq
Args:
current_rate: Current offered rate
target_rate: Desired rate
project_complexity: Complexity level (low, medium, high)
justification_points: List of points to justify higher rate
| Name | Required | Description | Default |
|---|---|---|---|
| target_rate | Yes | ||
| current_rate | Yes | ||
| project_complexity | No | medium | |
| justification_points | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It says the tool generates a strategy and message using an LLM, but does not disclose side effects, authentication needs, latency/cost implications, or whether it is read-only. It adds little beyond the basic generation concept.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The purpose is front-loaded in the first line, followed by a structured Args block. It is appropriately sized for a four-parameter tool, though the Langchain ChatGroq detail is implementation noise that could be omitted.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a four-parameter tool with no annotations and an output schema, the description covers purpose and all parameters adequately. However, it lacks usage context, edge cases, and any behavioral notes about the LLM-backed generation. It is minimally complete but has clear gaps in routing guidance.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate, and it does by documenting all four parameters in an Args block. It clarifies each field's meaning, including that project_complexity accepts low/medium/high and justification_points is a list. Units or format constraints for the rate fields are still absent, preventing a 5.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb+resource: generate a rate negotiation strategy and message. It is distinguishable from siblings like calculate_pricing_strategy or generate_proposal, but does not explicitly name alternatives. The implementation note about Langchain ChatGroq is extra but not harmful.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No when-to-use guidance, no prerequisites, and no alternatives are provided. The description only lists arguments, leaving the agent to infer when this tool is appropriate versus calculate_pricing_strategy or generate_proposal.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
optimize_profileB
Provide profile optimization recommendations using LLM analysis
Args:
profile_id: ID of the profile to optimize
target_niche: Specific niche to optimize for (optional)
| Name | Required | Description | Default |
|---|---|---|---|
| profile_id | Yes | ||
| target_niche | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral burden. It mentions LLM analysis but does not disclose side effects, permissions, rate limits, or whether the profile is modified; 'recommendations' hints at read-only but remains ambiguous.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the purpose and then lists the two arguments compactly. Every sentence earns its place, with no redundant or vague filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Output schema exists, so return values need not be explained. However, with no annotations and no usage guidance, the description is incomplete for safe invocation: an agent cannot tell when to choose this tool or what behavioral constraints apply.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It meaningfully explains both parameters: profile_id as the ID of the profile to optimize, and target_niche as the optional specific niche to optimize for.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb ('Provide') and resource ('profile optimization recommendations') and adds method ('using LLM analysis'). Clear enough to understand the tool, but it does not distinguish itself from sibling tools like analyze_profile_fit or get_smart_recommendations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. It only lists arguments, leaving usage context entirely implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
research_client_intelC
Research client quality and reliability
Args:
client_data: Client information (id, rating, reviews, total_spent, etc.)
Returns:
Detailed client intelligence report
| Name | Required | Description | Default |
|---|---|---|---|
| client_data | Yes |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It says nothing about permissions, whether the operation is read-only, rate limits, or side effects; it only states that a report is returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loads its purpose, followed by a compact Args/Returns structure. It contains no filler, though the return line is redundant given the existing output schema.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool accepting a nested client_data object with 0% schema description coverage, the description is incomplete: it does not explain expected input fields, required subfields, or usage context. The output schema makes the return description unnecessary, but the input side is underspecified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the only parameter is a nested object with no schema detail. The description partially compensates by listing example fields ('id, rating, reviews, total_spent, etc.'), adding some meaning beyond the bare schema, but the required structure and subfields remain vague.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('Research') and resource ('client quality and reliability'), making the tool's broad purpose clear. It does not explicitly differentiate itself from siblings like analyze_profile_fit or validate, so it falls short of a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no guidance on when to use this tool versus alternatives, no prerequisites, and no contextual triggers. Usage is only implied by the tool name and purpose.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
search_gigsC
Search for freelance gigs based on skills and criteria
Args:
skills: List of skills to match against
max_budget: Maximum budget/rate to filter by
min_budget: Minimum budget/rate to filter by
project_type: Type of project (fixed_price, hourly, retainer, contest)
platforms: List of platforms to search (upwork, freelancer, etc.)
use_real_api: Use real API integration (True) or mock data (False)
| Name | Required | Description | Default |
|---|---|---|---|
| skills | Yes | ||
| platforms | No | ||
| max_budget | No | ||
| min_budget | No | ||
| project_type | No | ||
| use_real_api | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing: not whether this hits external APIs, what the rate/quota behavior is, whether the mock-data path affects results predictably, or what happens on empty matches. The one genuine disclosure is the use_real_api real-vs-mock toggle, which is real context but far from sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The purpose line is front-loaded and the arg list is easy to scan, but much of it merely echoes the schema's own property titles (skills, max_budget, min_budget, platforms) instead of adding information, and the 'Args:' docstring format is not the most compact.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The output schema exists, so return values need not be described, and all six inputs are at least named. But for a six-parameter, annotation-free search tool that reaches external platforms, the description leaves usage context, matching semantics, and safety/behavioral details unstated.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate, and it does list every parameter with a terse gloss, including the project_type values and platform examples. However, it omits units/currency for budgets, matching semantics for skills (AND vs OR), and the default/effect of use_real_api beyond a one-line restatement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a clear verb+resource: 'Search for freelance gigs based on skills and criteria'. It is specific about what is searched, but it does nothing to distinguish itself from siblings like get_smart_recommendations or analyze_skill_demand, so an agent gets no routing help.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no when-to-use guidance, no prerequisites, and no mention of any alternative tool. The only contextual hint is the implicit 'search' framing, which does not tell an agent when this beats the recommendation or analysis siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
send_notificationB
Send notification through specified channel
Args:
channel: Notification channel (email, slack, discord, console, webhook)
title: Notification title
message: Notification message
data: Optional additional data
Returns:
Send status
| Name | Required | Description | Default |
|---|---|---|---|
| data | No | ||
| title | Yes | ||
| channel | Yes | ||
| message | Yes |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It says it returns send status but omits important behavioral details such as authentication requirements, rate limits, side effects, external delivery implications, or channel-specific behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Front-loaded with the core action and followed by a compact Args/Returns structure. Every line serves a purpose and there is no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has an output schema, so return values need not be fully explained. However, for a send operation with no annotations, the description leaves behavioral context (auth, side effects, failure modes) incomplete even for a simple notification tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It documents all four parameters and notably lists valid channel values (email, slack, discord, console, webhook) that the schema does not enumerate. The 'data' parameter remains vague as 'Optional additional data'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource: 'Send notification through specified channel.' The purpose is immediately clear. However, it does not differentiate from siblings, though no sibling tool appears to overlap in function.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, prerequisites, or channel selection criteria. The implied usage is sending a notification, but there are no explicit conditions or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
setup_auto_biddingB
Configure automatic bidding agent
Args:
enabled: Enable auto-bidding
min_match_score: Minimum match score (0-1)
max_bids_per_day: Maximum bids per day
min_budget: Minimum budget to consider
max_budget: Maximum budget to consider
auto_apply: Actually submit bids (True) or just draft (False)
skills: Required skills filter
Returns:
Auto-bid configuration status
| Name | Required | Description | Default |
|---|---|---|---|
| skills | No | ||
| enabled | No | ||
| auto_apply | No | ||
| max_budget | No | ||
| min_budget | No | ||
| min_match_score | No | ||
| max_bids_per_day | No |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose a meaningful behavior: auto_apply=True actually submits bids while False only drafts them. However, it omits permissions required, reversibility, whether enabling results in real-world spend, and any rate/impact caveats.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Front-loads the purpose, then a clean Args block with one line per parameter. No wasted prose, though the trailing 'Returns' line duplicates information the output schema already provides.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The output schema exists so return values need no explanation, and all seven params are covered. What is missing is the when-to-use context and prerequisite/impact information that a config tool with real-world bidding consequences should provide.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate and largely does: all seven parameters are described, including the crucial auto_apply draft-vs-submit distinction and the 0-1 range on min_match_score. The explanations are terse and slightly tautological ('Minimum bids per day'), which keeps this from a 5.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('Configure automatic bidding agent'), which is clear enough to select over unrelated siblings like generate_proposal or search_gigs. It does not, however, distinguish itself from any sibling explicitly or state scope limits.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description never says when to use this tool versus alternatives, nor prerequisites (e.g., must a profile exist first?). Agents get a field list but no routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
track_application_statusC
Track and analyze freelance application performance
Args:
applications: List of application data with status updates
| Name | Required | Description | Default |
|---|---|---|---|
| applications | Yes |
Output Schema
| Name | Required | Description |
|---|---|---|
| result | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden, yet it discloses nothing: it does not say whether this is a read-only analysis or persists state, whether 'status updates' mutate stored applications, what happens to prior data, or what permissions are needed. For a tool whose input contains 'status updates', the omission of any mutation/side-effect statement is a serious gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
It is short and the purpose sentence is front-loaded, but the 'Args:' block is boilerplate that conveys almost no information, and the overall brevity comes from under-specification rather than efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values need not be explained, but for a 1-required-param tool with no annotations and a fully undocumented nested payload, the description omits everything an agent needs to construct a valid call. It is far from complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the single parameter's item type is an untyped object with additionalProperties=true, so the schema documents nothing about the expected fields. The description only restates the param name with a thin gloss ('List of application data with status updates') and gives no field names, status values, or expected shape, so it fails to compensate for the coverage gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a resource ('freelance application performance') and verbs ('track and analyze'), so the general intent is inferable, but 'analyze' is vague and nothing distinguishes it from the 16 sibling tools (e.g., analyze_profile_fit, search_gigs, validate). It is a viable but undifferentiated statement of purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no guidance on when to reach for this tool versus siblings like validate, search_gigs, or analyze_profile_fit, and no prerequisites or exclusions are stated. The agent is left to guess from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Return the server owner's phone number in the required format:
{country_code}{number}
Example: 919876543210 (for +91-9876543210)
This reads one of:
- OWNER_PHONE (single env var containing the full digits, e.g. 15551234567)
- OWNER_COUNTRY_CODE and OWNER_PHONE_NUMBER (e.g. 1 and 5551234567)
It strips non-digit characters and returns the digits-only string.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the burden. It usefully explains the two env-var sourcing modes and that non-digit characters are stripped before returning. It does not explain failure behavior (what if OWNER_PHONE is unset), permissions, or error modes, which matters for a tool reading environment secrets.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The format requirement and example are front-loaded usefully, but the 'This reads one of:' block is verbose for two simple sourcing modes, and the description is longer than the underlying behavior warrants.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return structure need not be restated, but the description still restates the return format. It covers sourcing and stripping but omits failure behavior and the relationship to the 'validate' name, leaving the tool's actual purpose ambiguous.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool takes no parameters, so the baseline is 4. The description does add meaning about the implicit inputs (env vars OWNER_PHONE or OWNER_COUNTRY_CODE/OWNER_PHONE_NUMBER) that the schema cannot express.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description says it returns the owner's phone number in a specific format and reads it from env vars, which is a concrete resource. However, it never states the actual operation ('validate') ā the tool name suggests validation but the body describes retrieval/formatting. Purpose is stated for the side-effect, not the named tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to call this tool versus any sibling, nor any preconditions. The description explains mechanics but nothing about usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 17 tools
Most tools have distinct purposes, but there is overlap between search_gigs and get_smart_recommendations, and between analyze_profile_fit and calculate_pricing_strategy, which could cause confusion. The descriptions help differentiate them, but an agent might still misselect.
Most tool names follow a consistent verb_noun pattern, but there are exceptions like 'validate' (no noun) and 'send_notification' (verb_noun but slightly inconsistent with others). Overall, the naming is mostly predictable.
With 17 tools, the count is on the higher side for a freelance assistant but each tool appears to have a specific role. It's slightly heavy but reasonable for the domain's breadth.
The tool set covers many aspects like profile management, gig search, proposal generation, and code review, but lacks explicit tools for applying to gigs, managing contracts, or handling payments, which are core to freelancing. There are notable gaps that could hinder full workflow.
