coograph: Skill for Claude Code

.github/skills/coograph-apply/SKILL.md

coograph-apply is a skill for Claude Code from paullukic/coograph. It costs 27 tokens per session (1,036 once invoked), scanned A, original, MIT.

A workflow for implementing tasks listed in an OpenSpec change, a folder of files that describes a proposed software update.

In plain words
What is it for?
Use it to find an active change, review its context, implement its tasks, and verify the completed work.
Why use it?
It keeps implementation tied to the documented goals, requirements, acceptance checks, and task status instead of relying on guesswork.

Token cost

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.

Security

Grade A, and why

coograph-apply 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 9d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement tasks from an OpenSpec change in openspec/changes/.


Step 1: Identify the change

If a name is provided, look for openspec/changes/<name>/ or openspec/changes/<date>-<name>/.

If no name is provided:

  • List directories in openspec/changes/ (excluding archive/)
  • If only one active change exists, use it and announce: "Using change: "
  • If multiple exist, ask the user to select

Step 2: Read context

Read these files from the change directory:

  • proposal.md — goals, scope, decisions
  • specs/<capability>/spec.md — requirements and acceptance criteria
  • tasks.md — task list and completion status

If any file is missing, report which one and ask the user for its location. Do not confabulate contents.

Show current progress: "N/M tasks complete — working on: "

Step 3: Classify change size

  • Quick (≤3 tasks, ≤50 lines changed, no new files): skip full self-verification and auto-review — run a lightweight logic check instead.
  • Standard (everything else): run all verification and review steps.

Step 4: Implement tasks

CRITICAL: Follow tasks.md literally. Never reinterpret or regenerate tasks. Never invent field names, API types, or schemas that don't exist in the actual source code.

For each pending task:

  1. Announce which task is being worked on
  2. Read every source file to be modified — in full — before making any change
  3. Grep for every field/type name before using it. If a name cannot be found: STOP, report what's missing, ask the user
  4. Make the code changes
  5. Every task MUST result in actual file edits — if a task produces zero edits, it is not complete
  6. Mark complete in tasks.md: - [ ]- [x]

Pause if: task is unclear, implementation reveals a design issue, or an error is encountered.

Step 5: Self-verification (standard changes only)

Before invoking the Reviewer:

  1. Feature inventory: compare modified files against their original (git show HEAD:<path>). List features: PRESERVED or REMOVED. Restore any removed without explicit spec request.
  2. Spec text match: re-read the spec. Verify every requirement is implemented. Flag mismatches.
  3. i18n checks (if project uses i18n): verify new/changed keys exist in all language files.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
