evidence-gap-review

evidence-gap-review is a skill for Claude Code, Codex from 45ck/skill-harness. It costs 24 tokens per session (700 once invoked), scanned A, original, MIT.

A guide for reviewing specgraph verification results and finding missing evidence. Evidence means the annotations, tracked work, indexed records, tests, or CI artifacts that support a specification.

In plain words
What is it for?
Use it to inspect verification output, group evidence gaps by effort, and recommend annotations, tests, indexed artifacts, or approved waivers.
Why use it?
It explains why a specification is marked WARN, FAIL, or INSUFFICIENT and identifies the smallest action needed to improve its evidence.

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

evidence-gap-review 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review the output of specgraph verify (or specgraph verify --json) and produce an actionable gap report.

Procedure

  1. Run specgraph verify (or read the provided output).
  2. For each spec with status WARN, FAIL, or INSUFFICIENT:
    • Identify the required evidence dimension(s) that are unmet.
    • State the current evidence level and what level is needed.
    • Suggest the lowest-effort action that would provide the required evidence.
  3. Group findings by effort: low (annotation), medium (test), high (architecture decision).

Evidence-gap action map

Required level Unmet because Recommended action
E0 No @spec annotation Add /** @spec ID @implements Feature */ to the implementation file
E1 No closed Beads issue or structural artifact Create a Beads issue with --spec-id ID and close it when done
E2 Not indexed in specgraph DB / no linked artifact Run specgraph verify to store claims, add cross-refs via depends_on
E3 No test annotation Add /** @spec ID @verifies Feature */ to a test file
E4 No CI artifact Configure freshness.artifacts in .specgraph/config.json

Status meanings

Status Meaning
PASS All required evidence thresholds met
WARN Evidence exists but below required strength for this state
FAIL No evidence found for a required dimension
INSUFFICIENT Evidence found but strength is below required level (e.g. E0 found, E2 required)
SKIP Spec has no evidence requirements (draft/deprecated)
WAIVED Requirement waived — check expiry

Output format

For each gap, output:

SPEC-ID  [WARN|FAIL|INSUFFICIENT]  dimension=<name>  need=<Ex>  have=<Ey|none>
  → Action: <one-line description>

Then a prioritised action list (most impactful first).

Useful drill-down commands

specgraph verify                     # summary table for all specs
specgraph verify --json              # machine-readable output
specgraph verify --spec SPEC-ID      # single spec only
specgraph explain SPEC-ID            # full claim breakdown for one spec
specgraph find --spec SPEC-ID        # locate files that reference a spec
specgraph find --relation IMPLEMENTS # all IMPLEMENTS claims
specgraph find --strength 1          # E1 and above
specgraph waivers                    # list active waivers

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.

evidence-gap-review is a skill published in the GitHub repository 45ck/skill-harness (15 stars, last pushed 2mo ago), licensed MIT. It adds 24 tokens to every session and 700 once invoked, about $0.0001 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.
