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: 1 finding, up to medium
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 →
- medium Agent Snooping · line 10 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00052 | $0.00183 |
| Opus 5 | $0.00026 | $0.00092 |
| Sonnet 5 | $0.00010 | $0.00037 |
| Haiku 4.5 | $0.00005 | $0.00018 |
Grade A, and why
compact-communication 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 6d 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.
What it actually says
Compact Communication Contract — DEPRECATED
The runtime communication contract (default rules, preferred output patterns, auto-clarity exceptions, and exact-preservation boundaries) now lives in AGENTS.md under ## Communication Style. That section is loaded once per command as ambient context; no skill or sub-agent should Read this file.
This shim is kept so existing external references to the path do not break. The scripts/drift-report.mjs strict check fails any PR that re-introduces a Read .github/skills/compact-communication/SKILL.md instruction outside this file.
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.
- 6d ago First seen · 11 lines · 52 tokens per session scan A 5dfb59d62d63
compact-communication is a skill published in the GitHub repository attilaszasz/sdd-pilot (96 stars, last pushed 5d ago), licensed MIT. It adds 52 tokens to every session and 183 once invoked, about $0.0003 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 2026-09-03.
Other skills, from other repositories
code-review-hardening
Use this skill for rigorous, structured code review with a self-repair loop. Applies change-type-aware strategies (feat, fix, hotfix, refactor, migrate, docs). Findings are severity-classified, then auto-fixed where possible. Triggers on PR reviews, code review requests, or when reviewing any change set.
contextual-stewardship
Use this skill when the user makes a technical decision, establishes a new pattern, defines business rules, or explicitly asks to remember or save a guideline. Also use this skill when you are about to implement a feature, write code, plan an architecture, or make a technical decision - you MUST retrieve contextual…
project-guidelines-writer
Use this skill when the user wants repository guidance documents generated or refreshed, including AGENTS.md, CONTRIBUTING.md, STYLEGUIDE.md, TESTING.md, ARCHITECTURE.md, and SECURITY.md. It analyzes the repository, generates all six guideline files by default, prefers managed-section updates for existing files, and…
quality-grading
Use this skill to grade code, specifications, or design documents across four quality dimensions using a 1-5 scoring scale. In grade-and-fix mode, the skill auto-improves artifacts scoring below 5 without prompting. Invoke when you want consistent quality assessment on design, implementation, or specification with…
spec-driven-task-decomposer
Use this skill when approved requirements and design need to be decomposed into tasks.md for Phase 3 of a Spec-Driven change. It creates atomic, traceable implementation and testing tasks, validates the plan, and should not be used to design architecture or write implementation code.
universal-live-check
Universal live-check framework for coding agents. Executes incremental, deterministic validation across all software domains (CLI, backend, frontend, mobile, embedded, libs). Change-type-aware (feat, fix, hotfix, refactor, migrate, docs). Triggers whenever an agent needs to validate code quality, run linting, perform…
