fix(codex): restore Superpowers after compaction

Codex re-fires SessionStart with source "compact" after every context
compaction; the summary keeps progress but sheds the bootstrap and any
active skill's instructions — measured July cause of post-compaction
dispatch drift in long SDD runs (with re-injection: 18/18 hook fires,
66/66 post-compaction dispatch tuples correct in a 12.4h stress run).
Codex discovers skills natively at startup, so the hook is silent
there: the compact re-fire is the one unowned lifecycle point.

Adds the plugin-provided hook (hooks-codex.json + session-start-codex,
compact-only, fails open), wires it into the manifest and package,
documents install/trust behavior, updates codex-tools.md with the
re-grounding fallback, and tests the hook lifecycle, manifest, and
archive contents.

Rebuilt from the July codex-spinout-fixes branch, pared to the hook
core: the dispatch-hints layer it used to ride with is superseded by
the merged 2059-2062/2077-2080 stack and is dropped.

+#### Codex: compaction re-injection hook
+
+Codex compacts long sessions, replacing the transcript with a summary that
+drops Superpowers' skill instructions mid-run — long autonomous workflows
+(like subagent-driven-development) then drift back to harness defaults.
+Claude Code re-injects the bootstrap after every compaction; the plugin ships
+a SessionStart hook (`hooks/hooks-codex.json`) that restores the same
+behavior on Codex (0.145+). It fires only on post-compaction re-starts
+(`source: "compact"`) and is silent at normal session start.
+
+The hook installs with the plugin — no configuration needed. Codex asks you
+to review and trust it once, the first time it loads after install or update.
+Headless automation (CI, eval harnesses) must pass
+`--dangerously-bypass-hook-trust` instead, because untrusted hooks are
+skipped silently.

 Because skills and plugins don't provide any feedback to creators, we have no idea how many of you are using Superpowers. By default, the Prime Radiant logo on brainstorming's optional visual companion feature is loaded from our website. It includes the version of Superpowers in use. It does not include any details about your project, prompt, or coding agent. We don't see your clicks or anything about what you're building. This helps us have a rough idea of how many folks are using Superpowers and which version of Superpowers they're using. It's 100% optional. To disable this, set the environment variable `SUPERPOWERS_DISABLE_TELEMETRY` to any true value. Superpowers also honors Claude Code's `DISABLE_TELEMETRY` and `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` opt-outs.

-# Hermes Version-Bump Wiring Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Keep the Hermes YAML manifest version synchronized with every other declared release manifest.
-
-**Spec:** `docs/superpowers/specs/2026-08-05-hermes-version-bump-wiring-design.md`
-
-**Architecture:** Extend the existing release script with a small extension-based dispatcher: JSON continues through `jq`, while `.yaml` uses Mike Farah `yq` v4. Before the mutating bump loop, read every present manifest through that dispatcher so deterministic format or field failures occur before the first write.
-
-**Tech Stack:** Bash 3.2-compatible shell, `jq`, Mike Farah `yq` v4, existing shell-lint tooling.
-
-## Global Constraints
-
-- Support only `.json` and `.yaml`; `.yml` and other extensions remain unsupported.
-- YAML fields are present top-level strings; nested YAML fields are out of scope.
-- Pass the YAML field and new value through environment data, never interpolate either into a `yq` expression.
-- Keep `yq` confined to maintainer release tooling; do not add a plugin runtime dependency.
-- Preserve the existing missing-file behavior: `--check` reports missing files and a bump skips them.
-- Preflight only the mutating bump path; do not add rollback or transactional writes.
-- Do not change audit status behavior, version validation, or the existing JSON field-expression implementation.

-- [ ] **Step 7: Add the failing no-partial-write regression**
-
-Insert this block before the final success message in `tests/version-bump/test-bump-version.sh`:
-
-```bash
-invalid_repo="$TEST_ROOT/invalid"
-make_fixture "$invalid_repo" $'name: superpowers\nversion: 123'
-cp "$invalid_repo/package.json" "$TEST_ROOT/package.before"
-cp "$invalid_repo/.hermes-plugin/plugin.yaml" "$TEST_ROOT/plugin.before"
-
-if /bin/bash "$invalid_repo/scripts/bump-version.sh" 2.3.4 \
-  >"$TEST_ROOT/invalid.out" 2>&1; then
-  fail "bump accepted a non-string YAML version"
-fi
-
-cmp -s "$TEST_ROOT/package.before" "$invalid_repo/package.json" \
-  || fail "JSON manifest changed before YAML validation failed"
-cmp -s "$TEST_ROOT/plugin.before" "$invalid_repo/.hermes-plugin/plugin.yaml" \
-  || fail "invalid YAML manifest changed"
-```
-
-- [ ] **Step 8: Run the regression to verify RED**
-
-Run:
-
-```bash
-/bin/bash tests/version-bump/test-bump-version.sh
-```
-
-Expected: FAIL with `JSON manifest changed before YAML validation failed`; without preflight, the JSON manifest is written before the later YAML reader rejects its non-string version.
-
-- [ ] **Step 9: Add the bump-only preflight**
-
-Add this helper after `declared_files` in `scripts/bump-version.sh`:
-
-```bash
-preflight_manifests() {
-  local path field fullpath
-
-  require_tool jq || return 1
-  while IFS=$'\t' read -r path field; do
-    fullpath="$REPO_ROOT/$path"
-    [[ -f "$fullpath" ]] || continue
-
-    if ! read_manifest_field "$fullpath" "$field" >/dev/null; then
-      echo "error: cannot read declared manifest: $path ($field)" >&2
-      return 1
-    fi
-  done < <(declared_files)
-}
-```
-
-Call it in `cmd_bump` after version-format validation and before the first bump output or write:
-
-```bash
-  preflight_manifests
-
-  echo "Bumping all declared files to $new_version..."
-```
-
-- [ ] **Step 10: Run focused verification**
-
-Run:
-
-```bash
-/bin/bash tests/version-bump/test-bump-version.sh
-scripts/lint-shell.sh scripts/bump-version.sh tests/version-bump/test-bump-version.sh
-scripts/bump-version.sh --check
-git diff --check
-```
-
-Expected:
-
-- The behavioral test prints `Version-bump tests passed`.
-- Shell lint reports both scripts with no errors.
-- `--check` lists eight declared manifests, including `.hermes-plugin/plugin.yaml`, all at `6.2.0`.
-- `git diff --check` prints nothing.
-
-- [ ] **Step 11: Review and commit the implementation**
-
-Run:
-
-```bash
-git status --short
-git diff -- .version-bump.json scripts/bump-version.sh tests/version-bump/test-bump-version.sh
-git add .version-bump.json scripts/bump-version.sh tests/version-bump/test-bump-version.sh
-git commit \
-  -m "fix(release): wire Hermes into version bumps" \
-  -m "Register the Hermes YAML manifest alongside the existing JSON manifests. Route manifest reads and writes by extension through jq or Mike Farah yq v4, with field names and values passed as data." \
-  -m "Preflight every present manifest before the mutating bump loop so a deterministic YAML read failure cannot leave earlier JSON manifests partially updated. Cover check, audit, bump, registry wiring, and byte-for-byte no-partial-write behavior with one focused fixture test."
-```
-
-Expected: the commit succeeds with only the three implementation paths staged.

-# Codex Efficiency Fixes — Design
-
-Date: 2026-07-30
-Status: approved by Jesse (in-session)
-Branch: `codex-efficiency-fixes` off `dev`
-
-## Sources
-
-- Eval campaign closeout: `superpowers-autoresearch/reports/2026-07-codex-efficiency-campaign.md`
-  (treatment table §4; every treatment below has a scorer and a measured
-  `dev` baseline).
-- Codex source recon: `superpowers-autoresearch/docs/2026-07-29-codex-multiagent-v2-capabilities.md`
-  (file:line citations against the Codex CLI source; grounds T2, T3, T5).
-- Published experiment write-ups: `superpowers-evals/docs/experiments/`.
-- Drew's spinout stack (PRs #2036, #2035) is **evidence, not adopted text**:
-  Jesse wants to dig into those fixes in more detail before adopting any
-  of them; they inform the problem statements only.
-
-## Goal
-
-Ship the five evidence-strong treatments from the codex-efficiency eval
-campaign as superpowers skill/doc changes, each graded against its
-pre-registered criterion by the campaign's scorers before its PR is cut.
-Phase 2 (everything else in the closeout treatment table) follows, each
-item gated on new baseline work first.
-
-## Scope decisions (settled with Jesse)
-
-- **Phase 1 = the evidence-strong five** (T1–T5 below). Phase 2 items
-  each need a failing baseline before any fix ships (discrimination
-  rule: inconclusive-by-zero is a stop).
-- **One branch, PR per treatment.** Development and batteries happen on
-  `codex-efficiency-fixes`; when a treatment beats its criterion, it is
-  cut into its own PR against `dev` with its eval evidence. No merge
-  without Jesse's per-PR approval.
-- **T4 ships cross-harness with a global regression battery** (Claude
-  Code, Codex, Gemini), variant C shape: ceremony scales, approval never
-  does.
-
-## The five treatments
-
-### T1. SDD worker-review prohibition
-
-**Evidence:** 9/9 depth-2 spawns across 4 corpora were implementer-issued
-reviewers; all 9 were same-task duplicates of the review the controller
-dispatches anyway. The dispatch contract never says review is not the
-worker's job; "self-review" in the implementer prompt gets reified into a
-reviewer subagent on harnesses where children can spawn (Codex).
-
-**Changes:**
-- `skills/subagent-driven-development/implementer-prompt.md`: an explicit
-  "You do not dispatch subagents" clause — self-review means reading your
-  own diff; the controller owns all review dispatch; a reviewer you spawn
-  duplicates a review the process already provides.
-- `skills/subagent-driven-development/SKILL.md`: one dispatch-contract
-  line in the task loop, plus a Red Flags row: "An independent review
-  would strengthen my report" → review is the controller's next step;
-  your reviewer is a duplicate seat.
-- Harness-agnostic wording (no-op where children cannot spawn).
-
-**Graded by:** `score_e6.py` (depth-2 spawns by spawner role, duplicate
-review families); `score_e5.py` for the same-scope variant.
-**Baseline:** 9/9 worker-issued, 0 counter-examples.
-**Criterion:** 0 worker-issued depth-2 spawns AND review coverage
-preserved (every task still gets exactly one controller-dispatched task
-review).
-
-### T2. Event-driven waiting
-
-**Evidence:** 60–78% of `wait_agent` calls time out in every corpus
-(dev 67.1%, spinout 60.2%). Source recon: V2 waits are event
-subscriptions, not polls — one long wait has the same wake latency as a
-10s poll at ~1/90th the calls; a completed child's FINAL_ANSWER is pushed
-into the parent's mailbox and drained into the next model request with no
-wait at all.
-
-**Changes** (`skills/using-superpowers/references/codex-tools.md`):
-- Never short-timeout poll.
-- While local work remains, do not wait — child results arrive with your
-  next turn via the mailbox.
-- When genuinely idle, issue ONE `wait_agent` with a long `timeout_ms`
-  (900000+; harness max 3600000).
-- V2 caveat stated: completion mail carries `trigger_turn=false` and will
-  not wake an idle controller — that is the one job `wait_agent` has.
-
-**Graded by:** `score_e7.py` (timeout rate, inter-poll cadence,
-cache-rebill estimate — the rebill figure stays labeled as an estimate).
-**Baseline:** dev 67.1% timeout rate.
-**Criterion:** timeout rate < 25% with no loss of task completion.
-
-### T3. codex-tools.md corrections
-
-**Evidence:** five claims in the current guidance are contradicted by the
-Codex source (all file:line-cited in the capabilities doc):
-1. `close_agent` does not exist in multi-agent V2 (V1-only). V2 LRU-evicts
-   finished children automatically; not closing costs nothing;
-   `followup_task` transparently reloads an evicted child.
-2. Fix rounds can always resume the implementer via `followup_task` —
-   dev's "if your harness cannot send another message to a spawned agent,
-   dispatch each fix round as a fresh implementer" branch is dead on V2.
-3. Role files (`~/.codex/agents/**.toml`) DO attach to spawns via
-   `agent_type` on isolated forks (0.145+).
-4. Full-history forks accept `model`/`reasoning_effort` overrides; only
-   `agent_type` is refused. (Isolated forks remain the SDD guidance for
-   context-hygiene reasons, stated accurately.)
-5. Dispatch guidance must never name non-V2 model presets — the V2 spawn
-   allowlist is v2 presets only; others hard-error.
-
-**Changes:** rewrite the multi-agent paragraph of
-`skills/using-superpowers/references/codex-tools.md` to be
-version-honest (V1 vs V2 behavior labeled where they differ).
-
-**Graded by:** source citation (already verified); no scorer regressions
-on the shared battery. `score_e8.py` is retained as a V1/V2 schema
-detector, not a hygiene grader — no `close_agent` checklist ships.
-
-### T4. Brainstorming three-path router (variant C: approval always)
-
-**Evidence:** micro — the current HARD-GATE text pushes a bounded task to
-FULL ceremony 5/5, while Z-null (no guidance) and a three-path router
-both differentiate 5/5: the absolute wording suppresses discrimination
-the model draws natively. FULL battery — ceremony volume scales
-moderately (16.7 vs 24.0 tool calls, bounded vs arch), but the
-two-document ritual (spec file → plan file) ran unconditionally in every
-rep. The measured waste is the unconditional artifact ritual, not the
-approval gate.
-
-**Design (variant C):** three paths scale the ARTIFACT; every path keeps
-human approval before implementation:
-- **Spike** (feasibility question, explicitly throwaway): present the
-  question and the intended probe in 2–3 sentences, get a nod, go. No
-  docs. Findings return as a recommendation; anything built stays labeled
-  throwaway.
-- **Bounded** (well-scoped change to an existing, understood flow):
-  present a short design in chat, get approval, implement. No spec file,
-  no writing-plans invocation.
-- **Architectural** (restructures components, new subsystem, public
-  interface change): the full current flow — spec doc, review,
-  writing-plans.
-
-**Guards (all ship with the router):**
-- Classification is said out loud ("this looks bounded, so I'll present a
-  short design here rather than write a spec") so the human can override.
-- When in doubt between two paths, take the heavier one.
-- One-way ratchet: hidden complexity discovered mid-path upgrades the
-  path; never downgrade mid-task.
-- New Red Flags rows targeting classification-as-escape-hatch ("I'll call
-  it bounded to skip the doc").
-
-**Changes** (`skills/brainstorming/SKILL.md`): HARD-GATE keeps "no
-implementation before approval" and drops "regardless of perceived
-simplicity" as the ceremony driver; anti-pattern section reframed (the
-sin is skipping approval, not skipping documents); checklist steps 6–9
-become the architectural path; process-flow graph gains the router; Red
-Flags rows added. This is carefully-tuned content — the edit follows
-writing-skills methodology and ships only with the full eval evidence
-below.
-
-**Graded by (three layers):**
-1. **Micro** (`ceremony-path-micro.py`, adapted): variant C literal text,
-   plus adversarially ambiguous briefs the campaign never tested (a task
-   that pattern-matches bounded but hides a public interface change).
-   Criteria: spike/bounded/arch differentiate (≥4/5 per cell); ambiguous
-   briefs escalate to FULL (≥4/5); arch never downgrades (5/5).
-2. **Codex ceremony battery:** `cx-ceremony-{spike,bounded,arch}` on the
-   fix arm, 3 reps each, `score_e4.py` census. Criteria: bounded reps
-   show an approval turn but zero committed spec files and zero
-   writing-plans ritual; arch reps keep the full two-doc flow; spike reps
-   stay minimal.
-3. **Global regression battery:** the same three ceremony scenarios on
-   Claude Code and Gemini (rig work: those scenarios are currently
-   codex-gated), 3 reps each; plus the triggering acceptance check
-   ("Let's make a react todo list" auto-triggers brainstorming into the
-   full/architectural path) on all three harnesses.
-
-### T5. Explicit model on child-issued spawns
-
-**Evidence:** root spawns are 100% explicit-model at CLI 0.146 (dev
-14/14); the live gap is depth-2 — 2/2 child-issued spawns omitted
-`model`. Source recon: `model` without `reasoning_effort` resets effort
-to the MODEL's default, not the parent's.
-
-**Changes** (`skills/using-superpowers/references/codex-tools.md`):
-- Every spawn you issue — including as a child — sets `model` AND
-  `reasoning_effort`; the effort-reset trap is named.
-- Advise `[agents].default_subagent_model` and
-  `[agents].default_subagent_reasoning_effort` in `~/.codex/config.toml`
-  as the machine-level backstop for anything that slips through.
-
-**Graded by:** `score_e1.py` (per-spawn explicit-model rate, by depth) on
-the shared battery.
-**Baseline:** depth-2: 0/2 explicit.
-**Criterion:** every spawn at every depth carries explicit model +
-effort. Pre-registered caveat: if T1 eliminates depth-2 spawns entirely,
-T5 grades as root-spawn regression (hold 100%) plus doc correctness and
-is recorded inconclusive-by-zero at depth-2 — the config backstop is then
-the operative mechanism.
-
-## Grading plan
-
-- **Shared SDD battery** carries T1, T2, T5: `cx-sdd-small`, fix-branch
-  arm (`/tmp/sp-arm-fix`), 8 reps across both container lanes. Dev
-  baselines are already measured; no baseline re-runs.
-- **T4 batteries** as listed above (micro + codex ceremony + global
-  regression).
-- **Pre-registration:** every battery gets a hypothesis-log entry
-  (prediction, scorer, criterion) in
-  `superpowers-autoresearch/logs/2026-07-30-codex-efficiency-fixes.md`
-  BEFORE it runs. Standing rules carry over: append-only log, manual
-  inspection of scorer matches on fix-arm runs (non-circular
-  verification), no raw rollouts committed, correctness rides beside
-  cost in every verdict.
-- **Attribution:** orthogonal scorers on one combined branch; unexpected
-  regressions bisect by treatment commit.
-- **Budget:** shared battery ~$40, codex ceremony ~$40, global
-  regression ~$40–80, micros ~$5 → phase 1 ≈ $150–200 of the ~$850
-  remaining from the campaign's $1000.
-
-## Process
-
-- Work happens in the `codex-efficiency-fixes` worktree (branched off
-  `dev`); execution via subagent-driven-development from a written plan.
-- Skill-text changes follow writing-skills methodology.
-- Scenario/rig changes (un-gating ceremony scenarios for Claude
-  Code/Gemini, adversarial micro briefs) land in `superpowers-evals`
-  main, as authorized.
-- PR-per-treatment against `dev`, each with its eval evidence and the
-  standard identification block; merges only on Jesse's per-PR approval.
-
-## Phase 2 queue (baseline-first; not in this plan's tasks)
-
-Each item requires a failing baseline before any fix ships:
-1. **Dispatch routing / long-session drift** — needs a long-session
-   elicitation rig (fresh sessions don't reproduce the pathology at CLI
-   0.146). Drew's stack informs the treatment shape.
-2. **Verification leases / evidence receipts** — needs the
-   substring-aware duplicate counter added to `score_e3.py` first
-   (current baseline 1/23 exact-string pairs is too weak).
-3. **Remediation cap** — small-n baseline (2/3 reps) needs more reps.
-4. **Cross-task-race probe redesign** — `score_e5.py`'s probe is
-   inconclusive-by-zero by design tradeoff; needs a stronger probe.
-5. **E5 D4 shell-command parser** — fix-review-scope classifier cannot
-   parse compound commands; scorer work, not skill work.
-
-## Out of scope
-
-- Adopting Drew's spinout stack (#2036/#2035) or its text.
-- RoboRev, Codex token telemetry (separate codebases).
-- A `close_agent` hygiene checklist (V2 has no such tool — closed as
-  do-not-ship in the campaign).
-- Claude Code/Gemini-specific efficiency treatments beyond the T4
-  regression battery.

-# Hermes Version-Bump Wiring Design
-
-**Date:** 2026-08-05
-**Revised:** 2026-08-06
-**Status:** Approved
-
-## Goal
-
-Keep `.hermes-plugin/plugin.yaml` in lockstep with the repository version by
-registering it in `.version-bump.json` and teaching `scripts/bump-version.sh`
-to process YAML without implementing a YAML parser in Bash.
-
-## Design
-
-- Add `{ "path": ".hermes-plugin/plugin.yaml", "field": "version" }` to
-  `.version-bump.json`.
-- Route `.json` through the existing `jq` helpers and `.yaml` through Mike
-  Farah `yq` v4. The YAML key and value are passed as data, not interpolated
-  into the expression.
-- Support only a present top-level YAML string field. Nested fields and `.yml`
-  are out of scope.
-- Route `--check`, `--audit`, and version updates through the same small
-  read/write dispatcher.
-- Before a version bump writes any manifest, run one read-only preflight that
-  validates the required tools and reads every present declared manifest
-  through the dispatcher. This prevents a deterministic YAML failure from
-  occurring after earlier JSON files have already been updated. Missing-file
-  behavior remains unchanged, and `--help` still works without `jq` or `yq`.
-
-The preflight is the only reliability addition. It does not make the script
-transactional or redesign its existing audit and error-status behavior.
-
-## Tests
-
-Three focused behavioral tests run the real script against an isolated
-temporary fixture and prove:
-
-- aligned JSON and YAML pass `--check` and `--audit`, and a bump updates both
-  formats;
-- an actual bump with JSON declared first and a later YAML manifest whose
-  top-level `version` is not a string exits nonzero and leaves every manifest
-  byte-for-byte unchanged; and
-- the real `.version-bump.json` registers the Hermes manifest.
-
-Verification also runs shell lint and `scripts/bump-version.sh --check` against
-the repository.
-
-## Non-Goals
-
-- No hand-written YAML parser.
-- No `.yml` or nested-YAML support.
-- No Hermes runtime changes.
-- No rollback framework, general config-schema layer, audit/status refactor, or
-  exhaustive failure matrix.
-- No change to the separate version-validation and JSON-expression issue found
-  during review.

+## Anti-Pattern: "This Is Too Simple To Need A Design"
 
-Before your first question, classify the request and say the
+Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
-classification out loud — "this looks bounded, so I'll present a short
-design here rather than write a spec" — so your human partner can
-override it:
-
-- **Spike** — a feasibility question ("can we...", "is it possible...",
-  "quick and dirty is fine") whose output is an answer, not code you
-  keep. Present the question and what you'll try in 2-3 sentences, get
-  a nod, then find out as cheaply as correctness allows. No design
-  doc, no spec file. Report findings as a recommendation; anything you
-  built stays labeled throwaway.
-- **Bounded** — a well-scoped change to code that already exists in
-  this repo: a new flag, a small endpoint, a one-file fix.
-  Understanding the kind of app is not enough — bounded means the flow
-  you are changing is already here to read. If there is no existing
-  flow to change, the task is not bounded. Ask the clarifying
-  questions that matter, present a short design IN CHAT (a few
-  sentences to a few short paragraphs), and STOP. Implementation
-  starts only after your human partner says yes to that design — a
-  bounded task's approval is as hard a gate as an architectural
-  one. No spec file, no implementation plan document.
-- **Architectural** — new projects, new subsystems, changes that
-  restructure how components fit together or alter interfaces others
-  depend on. Follow the full process: questions, approaches, sectioned
-  design, written spec, then the writing-plans skill.
-
-When in doubt between two paths, take the heavier one. The ratchet is
-one-way: hidden complexity discovered mid-task upgrades the path —
-stop, say so, and step up. Nothing downgrades mid-task.
-
-## Anti-Pattern: "Too Simple To Need Approval"
-
-Every path ends with your human partner approving your intent before
-implementation. A todo list, a single-function utility, a config
-change — the design may be two sentences in chat, but you MUST present
-it and get approval. "Simple" tasks are where unexamined assumptions
-cause the most wasted work. What scales with simplicity is the
-artifact, never the approval.
-
-## Red Flags
-
-| Thought | Reality |
-|---------|---------|
-| "This is too simple to need a design" | Simple means a short design, not no design. Two sentences in chat, then approval. |
-| "I'll call it bounded and skip the spec" | Reaching for a label to skip work IS the doubt — take the heavier path. |
-| "It's bounded and the design is obvious — I'll start while they read it" | The gate is the approval, not the design's length. Present, then stop until you hear yes. |
-| "I understand this kind of app, so it's bounded" | Bounded measures the repo, not your familiarity. A new project has no existing flow — it is architectural. |
-| "The spike works, so I'll keep the code" | A spike's output is an answer. Keeping the code is a new request — classify it. |
-| "It grew, but I'm almost done — no need to re-classify" | Hidden complexity upgrades the path mid-task. Stop and say so. |
-| "They approved the spike, so the follow-up change is approved too" | Each task gets its own classification and its own approval. |

-# Hermes Agent Tool Mapping
-
-Skills speak in actions ("dispatch a subagent", "create a todo", "read a file"). On Hermes Agent these resolve to the tools below.
-
-## Tools
-
-| Action skills request | Hermes tool |
-|---|---|
-| Read a file | `read_file` |
-| Create a new file | `write_file` |
-| Edit a file (targeted patch) | `patch` |
-| Run a shell command | `terminal` |
-| Search file contents | `search_files` |
-| Find files by name | `terminal` with `find` |
-| Fetch a URL / read a webpage | `web_extract(urls=[...])` |
-| Search the web | `web_search(query=...)` |
-| Dispatch a subagent | `delegate_task(goal=..., context=..., toolsets=[...], role="leaf")` |
-| Task tracking | `todo` tool |
-| Invoke a skill | `skill_view("skill-name")` |
-
-## Instructions file
-
-When a skill mentions "your instructions file," on Hermes Agent this is **`AGENTS.md`** in the project directory, or **`SOUL.md`** globally at `~/.hermes/SOUL.md`.
-
-## Invoking a skill
-
-Hermes Agent has a `skills` toolset with `skill_view` and `skills_list` tools.
-To invoke a superpowers skill, use:
-
-```
-skill_view("brainstorming")
-skill_view("test-driven-development")
-```
-
-If `skill_view` cannot find a superpowers skill (it may not appear in the catalog
-until the plugin fully registers it), fall back to reading the SKILL.md directly:
-
-```
-read_file(path="~/.hermes/plugins/superpowers/skills/<skill-name>/SKILL.md")
-```
-
-This fallback is the same mechanism used by other harnesses without native skill loading.
-
-## Subagent dispatch
-
-Use `delegate_task` to spawn isolated subagents for parallel or sequential workstreams:
-
-```
-delegate_task(goal="...", context="...", toolsets=[...], role="leaf")
-```
-
-If `delegate_task` is unavailable, do the work inline rather than inventing tool calls.
-
-## Task tracking
-
-Use the `todo` tool for task tracking within a session. For multi-agent task boards, use `hermes kanban` CLI if available. Treat older `TodoWrite` references as the task-tracking action.
