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.

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 | $0.00047 | $0.01096 |
| Opus 5 | $0.00023 | $0.00548 |
| Sonnet 5 | $0.00009 | $0.00219 |
| Haiku 4.5 | $0.00005 | $0.00110 |
Grade A, and why
project-learnings 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 4d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Learnings
Capture project-specific patterns and anti-patterns into the project's CLAUDE.md. This creates a self-improving feedback loop where discoveries from debugging, development, and review make future Claude sessions smarter.
CRITICAL: Only project-specific knowledge qualifies. Generic programming advice does not belong in CLAUDE.md.
Step 1: Evaluate Discovery
Determine if the finding qualifies as project-specific. The finding must pass at least ONE of these criteria:
| Criteria | Example That Qualifies | Example That Doesn't |
|---|---|---|
| Would a developer unfamiliar with this project likely hit this issue? | "The processOrder() function expects amounts in cents, not dollars" |
"Always validate function inputs" |
| Is this pattern specific to this codebase's architecture, APIs, or conventions? | "The UserProfile type has an optional metadata field that is always present at runtime" |
"Use TypeScript strict mode" |
| Is it something Claude's training data wouldn't cover? | "Never call db.query() without the timeout option — the default is infinite" |
"Use async/await instead of callbacks" |
If NO to all criteria → STOP. Do not add generic programming knowledge to CLAUDE.md. Return to the calling skill and report that no project-specific learning was found.
If YES to any → proceed to Step 2.
Step 2: Read Existing CLAUDE.md
-
Find the project's CLAUDE.md:
- Check the repository root first
- If not found, check if there's a project-level
.claude/directory
-
Parse existing content:
- Understand the existing structure, headings, and conventions
- Look for sections where this learning would fit (e.g., "Known Gotchas", "Bug Patterns", "Conventions", "Known Challenges")
- Check for duplicate or similar entries already present
-
If a similar entry already exists → STOP. Report to the calling skill that this knowledge is already captured. Do not create duplicates.
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.
- 4d ago First seen · 118 lines · 47 tokens per session scan A e007b351f6c5
project-learnings is a skill published in the GitHub repository sequenzia/agent-alchemy (43 stars, last pushed 3mo ago), licensed MIT. It adds 47 tokens to every session and 1,096 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
Other skills, from other repositories
claude-code-session-broker
Use when running Arcgentic V2 in Claude Code and fixed Planner, Developer, and Auditor role sessions must be coordinated through a broker.
arcgentic
Use when the user says Arcgentic, asks to use Arcgentic, or wants an idea taken through a complete plan → development → self-audit → external audit workflow in Codex.
verify-gates
Runs the mechanical quality gates that the arcgentic state machine requires for state transitions. Invoked indirectly by transition.sh OR directly by orchestrator agent before declaring a state transition. Use when about to call transition.sh OR when manually verifying that a round artifact meets the gate criteria.…
session-mode
Use when a project has not yet stored session mode, when a user asks for complete arcgentic workflow execution, or when role identity handoff prompts are needed.
agency-roster
Use when a round references agency-agents catalogs, role-family routing, multi-agent identity prompts, or English/Chinese specialist role catalogs.
cross-session-handoff
Read, write, snapshot, and lock .arcgentic/state.yaml across planner, dev, audit, and optional test sessions.
