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 Rogue Agent · line 36 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.
- high Tool Misuse · line 57 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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 | $0.00024 | $0.02619 |
| Opus 5.5 | $0.00010 | $0.01048 |
| Sonnet 5.5 | $0.00005 | $0.00524 |
| Haiku 4.5 | $0.00002 | $0.00262 |
Grade A, and why
feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/feature — Create a Feature Request Ticket
Writing: read docs/skills/shared/writing-rule.md before you write a durable artifact.
Creates a structured GitHub Issue for a new feature with a user story, acceptance criteria, and design notes. Asks guided questions, shows the formatted ticket for confirmation, then creates the issue.
Path resolution
Read the registry path via portfolio_registry, the per-project docs dir via portfolio_projects_dir, and the ideas backlog via portfolio_ideas_backlog — all from .claude/hooks/_lib-portfolio-paths.sh. Source the helper at the top of any bash block that touches those paths:
source "$(git rev-parse --show-toplevel)/.claude/hooks/_lib-read-config.sh"
source "$(git rev-parse --show-toplevel)/.claude/hooks/_lib-portfolio-paths.sh"
registry=$(portfolio_registry)
Defaults match today's single-fork layout (./apexyard.projects.yaml, ./projects, ./projects/ideas-backlog.md). Adopters in split-portfolio mode override the portfolio.{registry, projects_dir, ideas_backlog} keys in .claude/project-config.json. Don't hardcode literal apexyard.projects.yaml or projects/ paths in bash blocks — the helper resolves whichever mode the adopter is in. See docs/multi-project.md.

Process
0. Write the active-issue-skill marker (REQUIRED — me2resh/apexyard#268)
Before any gh issue create (or other tracker CLI), write this skill's name to the active-issue-skill marker so require-skill-for-issue-create.sh lets the command through. At skill entry:
# Ops root through the session pin (docs/skills/shared/ops-root.md).
ops_root=$(p="${APEXYARD_OPS_PIN_DIR:-$HOME/.claude/apexyard}/ops-root-${CLAUDE_CODE_SESSION_ID:-}"; r=""; [ -z "${APEXYARD_OPS_DISABLE_PIN:-}" ] && [ -f "$p" ] && IFS= read -r r < "$p"; [ -f "$r/.claude/hooks/_lib-ops-root.sh" ] || { r="$PWD"; while [ -n "$r" ] && [ ! -f "$r/.claude/hooks/_lib-ops-root.sh" ]; do r=${r%/*}; done; }; [ -f "$r/.claude/hooks/_lib-ops-root.sh" ] && . "$r/.claude/hooks/_lib-ops-root.sh" && resolve_ops_root) && [ -n "$ops_root" ] || { echo "No ops root. See docs/skills/shared/ops-root.md." >&2; exit 1; }
mkdir -p "$ops_root/.claude/session"
echo "feature" > "$ops_root/.claude/session/active-issue-skill"
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.

feature is a skill published in the GitHub repository me2resh/apexyard (533 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 2,619 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 2026-08-30.
