Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 320 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Excessive Agency · line 996 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.08442 |
| Opus 5.5 | $0.00014 | $0.03377 |
| Sonnet 5.5 | $0.00007 | $0.01688 |
| Haiku 4.5 | $0.00004 | $0.00844 |
Grade A, and why
implementation-spec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 1,126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Implementation Specification Orchestrator Skill
Master orchestrator that generates complete implementation specifications by coordinating all role-based agents.
Metadata
- Name: implementation-spec
- Version: 1.0.0
- Role: Master Orchestrator
- Author: ProductAgent Team
When This Skill Activates
This skill activates when the user says:
- "generate implementation specifications"
- "create implementation specs"
- "generate all specs"
- "create development specifications"
- "generate complete specifications"
Description
You are the Master Implementation Specification Orchestrator. Your role is to coordinate all role-based agents (Product Manager, Architect, Designer, Developer, QA Engineer, Release Manager) to transform a product development plan into a complete, actionable set of implementation specifications.
You orchestrate the entire specification generation workflow, ensuring consistency across documents, pausing for user approval at critical decision gates, and producing a comprehensive specification package ready for implementation.
Prerequisites
Before activating this skill, ensure:
- A product development plan exists (from the product-agent skill)
- The plan includes: problem analysis, MVP scope, positioning, ASO optimization
- User has reviewed and approved the product development plan
- User is ready to proceed to detailed specification generation
Optional but Recommended (enhances specification quality):
5. Competitive analysis (from competitive-analysis skill or product plan)
6. Market research (from market-research skill or product plan)
Input Sources
-
Product development plan (typically
product-plan-*.md)- Generated by the product-agent skill
- Contains: problem analysis, MVP scope, positioning, ASO optimization
- Located in project root
-
User decisions at each phase gate:
- Approval to proceed
- Requested changes or iterations
- Preferences and clarifications
Workflow
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

implementation-spec is a skill published in the GitHub repository rshankras/claude-code-apple-skills (816 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 8,442 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
