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

feature-spec-revise 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 5d 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.

Origin

This is a copy

97% identical to afsrv — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

aigon-feature-spec-revise

You are the author-side agent. Review all pending spec-review: commits on the feature spec, decide what to keep, and land one acknowledgement commit.

The continuity strategy is selected by Aigon before launch. Do not choose a provider or resume strategy yourself. When resumed, reconcile remembered paths against the current checkout and emit the requested continuation ready/fallback checkpoint before editing.

Resolve the spec

SPEC_PATH=$(aigon feature-spec {{args}} 2>/dev/null || true)
if [ -z "$SPEC_PATH" ]; then
  SPEC_PATH=$(find docs/specs/features -maxdepth 2 \( -name "feature-{{args}}-*.md" -o -name "feature-{{args}}.md" \) | head -1)
fi
test -n "$SPEC_PATH" && echo "$SPEC_PATH"

If SPEC_PATH is empty, stop and report that the feature spec could not be resolved.

Find pending review commits

Find the latest acknowledgement, if any:

LAST_ACK=$(git log --follow --format=%H -n 1 --grep='^spec-review-check:' --grep='^spec-revise:' -- "$SPEC_PATH")
echo "last_ack=${LAST_ACK:-none}"

Then inspect pending reviews newer than that acknowledgement:

git log --follow --format='%H %s' -- "$SPEC_PATH"

Pending reviews are commits whose subject starts with spec-review: and are newer than LAST_ACK if LAST_ACK exists.

For every pending review commit:

git show <sha> -- "$SPEC_PATH"
git show -s --format=%B <sha>

Decide in one pass

Process all pending reviewers together. Your options are:

  • Accept: keep the reviewed spec as-is.
  • Revert: revert one or more review commits.
  • Modify: keep the reviewer intent but make follow-up edits before acknowledging.

If you need changes, make them before the acknowledgement commit.

Acknowledge with one commit

After the spec is in its final state, commit exactly once with:

git add "$SPEC_PATH"
git commit --allow-empty -m "spec-revise: feature {{args}} — <decision summary>" -m "reviewed: <comma-separated reviewer ids>

Decision:
- <accept|revert|modify summary>

Notes:
- <important rationale>"

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.
