known-issues-format

A format guide for thin-index ledgers: an index file that points to separate records for known defects and planned work.

In plain words
What is it for?
Use it to create or update project defect and work-item ledgers such as KNOWN_ISSUES.md and BACKLOG.md.
Why use it?
It keeps issue and backlog lists compact while preserving detailed records in predictable files.

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

known-issues-format 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check_contract_sync.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Thin-Index Ledger Format

Purpose: the single source of truth for the format of this framework's two hand-maintained thin-index ledgers — an index file whose every entry is one pointer line to its own record file:

Defects Work-items
Index docs/KNOWN_ISSUES.md docs/BACKLOG.md
Records docs/issues/<slug>.md docs/backlog/<slug>.md
Holds reproducible wrong behavior enhancement / polish / signal, no broken contract
Read by Analysis phase (avoid repeating bugs), /heal-issues Planning phase, humans ranking work
Written by run-feedback file --as defect run-feedback file --as work-item

artifact-management owns the lifecycle of both (living Global Artifacts, never archived, create-if-absent) and delegates the format to this skill — mirroring how it delegates ARCHITECTURE.md structure to architecture-format-core.

On the name. This skill began as the KNOWN_ISSUES.md contract and kept its name when the backlog joined it (four repositories symlink this directory by name). One skill, because the mechanics are one thing said once: two near-identical format contracts are exactly the drift that produced the defect this generalization fixed (run-feedback's two filing paths diverged — the defect path wrote index + record, the work-item path inlined the whole body into the index).

Execution Mode

  • Mode: hybrid — a prompt-first format contract, plus one maintenance gate script.

Script Contract

  • Command: python3 scripts/check_contract_sync.py
  • Purpose: fail if the format contract drifts between this SKILL.md (the authority) and the seed templates — per registry, it compares the status vocabulary, the rank vocabulary (severity / effort), the record frontmatter key set, and the index-line format.
  • Outputs / failure semantics: exit 0 in sync · 1 drift (prints the registry and the diverging field) · 2 extraction error.
  • Idempotent, read-only, no args, no dry-run needed. CI-gateable alongside System/scripts/validate_skills.py.

What ships with it

4 files 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.

known-issues-format is a skill published in the GitHub repository MatrixFounder/Agentic-development (5 stars, last pushed 19d ago), licensed Apache-2.0. It adds 103 tokens to every session and 3,727 once invoked, about $0.0005 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 2026-08-31.
