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: 3 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 Rogue Agent · line 3 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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 | $0.00074 | $0.02439 |
| Opus 5.5 | $0.00030 | $0.00976 |
| Sonnet 5.5 | $0.00015 | $0.00488 |
| Haiku 4.5 | $0.00007 | $0.00244 |
Grade A, and why
maintenance-rules 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.

skill-forge Maintenance Rules
Constraints and procedures for maintaining the skill-forge repository.
Execution Procedure
maintain(trigger) → updated | no_change
if "platform registry" in trigger:
update_platform_registry()
update_downstream() # SKILL.md Fix Phase, README install, Detection logic
if "community tools" in trigger:
update_community_tools()
if change proposed:
run_decision_test() # 7 criteria → accept | reject
verify_constraints() # each MUST's parenthesized method
run_consistency_checks()
update_changelog() # max 5, trim oldest
after significant changes:
run_self_governance() # 4 steps
Constraints
- MUST run Decision Test (7 criteria below) before accepting any change
- MUST NOT push SKILL.md body over 500 lines
- MUST keep SKILL.md ↔ README ↔ references terminology consistent
- MUST add References section entry when adding new reference files
- MUST update "Dependencies" table in README when SKILL.md dependencies or setup.sh changes
- MUST NOT include content that fails the Positional Test (see references/skill-format.md)
- MUST verify reference files follow three-layer format (frontmatter + EP + aligned Content)
- MUST keep examples in standard-defining references generic — no skill-forge-specific labels in universal patterns
- MUST verify SKILL.md pseudocode function names align with sub-module EP entry signatures (run: grep function names from references/ EPs, diff against SKILL.md pseudocode calls)
- MUST verify lossless delegation when moving inline criteria to a sub-module: map every deleted parent line to a sub-module EP line. Unmapped criteria → add to sub-module first, then remove from parent (run: diff parent before/after, match each removed line to a sub-module line)
- MUST verify every defined standard has a corresponding enforcement check in Validation (Structure, Quality, or Publishing). A standard without a check is dead weight — either add the check or remove the standard
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.
- 1mo ago First seen · 122 lines · 74 tokens per session scan A 66eb76cd8859
maintenance-rules is a skill published in the GitHub repository motiful/skill-forge (46 stars, last pushed 3mo ago), licensed MIT. It adds 74 tokens to every session and 2,439 once invoked, about $0.0003 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 2026-08-30.
Other skills, from other repositories
managing-mcp-servers
Use when the user asks to add, change, remove, enable or disable an MCP server, or when an MCP tool is missing, needs sign-in, fails, or was blocked. ThinkRail runs pi in-process, so there is no pi command to call.
output-standards
Use this skill when defining or enforcing output formatting standards for agent responses in WrongStack. Triggers: user says "next steps format", "output standard", "response format", "final message format", "standardize next steps".
todos
Use when the user asks for a shared plan, a task needs at least three substantive execution steps, or a loose TODO is pending. Without an explicit plan request, not for one-shot answers or checks, or one- to two-step work that is not already in the list.
web-platform-baseline
Use this skill before asserting that a CSS, HTML or accessibility capability is available, unavailable, or the right tool — it carries dated, refreshable platform facts and refuses to let stale knowledge be stated as current. Triggers: user says "container query", "can I use", "browser support", "modern CSS", ":has"…
codex-adversarial-review
Use this skill to conduct aggressive, adversarial code reviews on git changes, branches, or PRs to detect critical edge cases, race conditions, security holes, and data loss risks. Triggers: user mentions "adversarial review", "break the code", "find vulnerabilities", "security audit PR", "race condition check", "ship…
writing-workflow-skills
Use when adding a new workflow skill to pi-thinkrail-workflow, changing an existing workflow skill's role, trigger, handoff, or structure, or checking a workflow skill against the workflow system's rules. Not for authoring general-purpose skills outside this package.
